I am an old-school mainframe programmer, specializing in machines that use IBM z/Architecture and predecessors. This includes, but is not limited to, the following operating systems:

• z/OS, including UNIX System Services
• z/VSE
• z/VM
• Linux
• BS2000/OSD
• z/TPF

My speciality is assembler and C programming, but I am an expert in most other languages and tools found on these platforms, including COBOL, PL/I, Rexx, TSO CLIST, Fortran, ISPF…

I live in Roseville, California, USA.
